miro_update_app_card

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations are minimal (only title), so the description must disclose behavioral traits. It only says 'Update', implying mutation, but does not mention permissions, idempotency, side effects, or any constraints. The 'VOICE-FRIENDLY' example adds noise rather than clarity.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Very concise with two clear sentences. The 'VOICE-FRIENDLY' line is somewhat extraneous but does not significantly detract. Front-loaded with the main action.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given 9 parameters, all described in schema, the description covers only a subset (title, description, status, custom fields) and ignores x, y, width. An output schema exists but is not referenced. The tool has many siblings; the description fails to provide complete context for correct usage.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so baseline is 3. The description adds value by listing updatable fields (title, description, status, custom fields) but omits x, y, width. This partial addition justifies a 3.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'Update' and the resource 'app card', listing specific fields (title, description, status, custom fields). It distinguishes from siblings like miro_update_card by specifying 'app card', though not explicitly contrasting them.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives (e.g., miro_update_card, miro_update_item). The description simply states what it does, omitting context about prerequisites or situational use.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
